Yeastar O2 FXO Module: Essential Solution for External Line Connectivity

The Yeastar O2 FXO Module is key hardware used to connect traditional analog phone lines (PSTN) to Yeastar IP PBX systems. Each O2 module adds 2 FXO ports to your PBX, letting you integrate existing external lines into your IP-based system. This module lets businesses keep legacy analog line investments while benefiting from advanced IP PBX features. When analog connectivity is still required for external lines, the O2 FXO module acts as a seamless, reliable bridge. ---

FXO VoIP Gateway vs Yeastar O2 Module

Businesses that want to integrate analog phone lines (PSTN) into IP-based phone systems have two main options: use an analog VoIP gateway or install FXO modules such as O2 on an existing IP PBX. The better choice depends on your current infrastructure, PBX model, scalability needs, and budget. If you already have a module-capable IP PBX such as Yeastar, adding an O2 FXO module is usually a more integrated, easier-to-manage solution. This approach manages all lines from one interface and typically requires lower additional hardware cost because you do not need a separate gateway device or extra network configuration. However, if your PBX does not support modules or you want to connect analog lines at a different location to a central IP PBX, an analog VoIP gateway can be a more flexible, practical solution. Gateways work as standalone devices compatible with PBXs from different brands and can easily bring remote analog lines to the center. The final decision should follow a detailed analysis of your business needs and current communication infrastructure.

Yeastar O2 FXO Module: Compatible PBX Models and Capacities

The Yeastar O2 FXO module is compatible with various Yeastar IP PBX models and offers different analog line capacities depending on each system's module slot count. This modular structure gives businesses flexibility as needs grow.

Compatible Yeastar IP PBX Models and Supported O2 Module Counts

• Yeastar S-Series PBXs:
  • S20, S50, S412: These compact models usually have module slots on the main board. S20 and S50 can support up to 2 O2 modules (4 FXO ports total), and S412 offers similar capacity.
  • S100, S300: Higher-capacity S100 and S300 models support more modules via EX08 expansion cards in addition to direct module slots. Up to 4 O2 modules can be installed on each EX08 card. Up to 2 EX08 cards can be added to S100 and up to 3 to S300, significantly increasing analog line capacity.
• Yeastar P-Series PBXs:
  • P520: Designed for small businesses, it usually has up to 4 module slots. Up to 4 O2 modules can be installed on P520 for 8 FXO ports total.
  • P550: Usually has up to 4 module slots, so up to 4 O2 modules (8 FXO ports total) can be installed.
  • P560, P570: These upper P-Series models offer more modularity and expansion. P560 supports one expansion card; P570 supports two. O2 modules on expansion cards enable much higher analog line capacity. For example, maximum FXO/BRI ports on a P570 can reach 16, meaning multiple O2 modules can be used.
• Yeastar MyPBX Series:
  • Earlier Yeastar MyPBX models (MyPBX SOHO, MyPBX Standard, MyPBX Pro, MyPBX E1/E1 Plus, MyPBX Enterprise) are also compatible with the O2 module; the number of O2 modules varies by model.

Because each O2 module provides 2 FXO ports, the number of O2 modules a PBX supports directly determines maximum analog external line capacity. Refer to Yeastar official product documentation or your PBX model's technical specifications for the latest, exact capacity information.
